Shared Content on Mac OS has wrong permissions
UE4 now installs the engine content at
If you manually change the permissions of that folder to give everyone read/write, then it doesn't hang, though it does re-download the engine.

This is a known issue with the Launcher that is reported in our bug database (OPP-1601). For now, the root admin user will need to download any engine updates or content from the Launcher. You should still be able to use the engine on other accounts, however. If you navigate to the installed version of the engine and go to Engine > Binaries > Mac, you can run the UE4Editor.app to open that version of the editor. Hope that helps!
